Definitions

  • the invention relates to a hull of composable elements of an aluminum material, wherein plank-like, at least parts of the outer shape of the hull forming and tailored according to their intended outline elements are welded together at their adjacent edges extending in the ship's longitudinal direction.
  • hulls made of aluminum materials for ships of this size are usually made by hand, which is relatively large, especially because of the welding work occurring possibly occurring welding distortion and temporarily welded aids Rework requires.
  • a smooth and firming surface of a hull made of an aluminum material is therefore often reachable only by a considerable effort in the form of spatulas and loops, wherein the thickness of the applied plastic putty sometimes the Can exceed sheet thickness.
  • the additional weight of the putty and the laborious work thereby the otherwise excellent recycling properties of aluminum are severely limited.
  • a hull of the type mentioned with a welded together consisting of several aluminum alloy planks fuselage known.
  • the thickness of the aluminum plates used to create the fuselage is chosen with at least 12 millimeters at a ship length of about 10 to 12 meters so that the hull is dimensionally stable without any Spantiana and can be used in this form.
  • a significant weight penalty resulting from the wall thickness required in this construction, a significant weight penalty.
  • welding devices and molds are required to hold and staple the planks in a welding position.
  • a hull made of metal in particular made of aluminum, in which an inner body of a fiberglass construction is used and connected to a peripheral upper edge region with the metal hull.
  • the hull has the typical shape of a So-called kink chip with a Chine-like intermediate area between a side area and the ship's bottom and is equipped with regularly spaced frames and a number of longitudinal stiffeners.
  • plate-first method describes a method in which, with the aid of a 3D CAD model, the plates forming individual plank elements are cut to size according to their respective desired contour and arranged so that they anchor after being positioned on devices, stapled and finally welded together. This can be done according to the method described in this reference initially without the presence of a bulkhead, which is inserted in the case of this known hull only then in the finished fuselage and welded.
  • a major advantage of this approach is that it allows the already mentioned unsightly deformations of the outer skin of the hull, as they can occur when welding the plank elements with the associated frames largely avoided.
  • a hull of the type mentioned in such a way that it can be created in a simple and reliable manner from prefabricated elements as a modular system.
  • the invention solves this problem by providing that the hull consists of the hull and a structure made as a separate unit and fastened to it by means of identical flange plates.
  • the in the preferred embodiment of the invention parallel to the water surface circumferential connection of the two flange plates is preferably arranged at an optimum height above the waterline of the hull and also serves as a support for lateral Fenderprofile.
  • the invention makes it possible in this way to produce hulls for various uses without much modification by combining the hull made of an aluminum material with structures different in shape and material, the different structures each being arranged on identical flange plates as a base.
  • Advantageous developments of the hull according to the invention are specified in the further claims.
  • the former elements are already folded before their assembly in each case to an individually shaped hat profile that their side surfaces are everywhere perpendicular to the lateral surface of the hull after successful assembly and that they are predetermined by Indexierbohronne, moreover, are positioned in a uniform Spantabstand, so that for the subsequent screwing the associated gusset plates and Bodenwrangen each lie on the same cross-sectional plane.
  • the bolted gusset plates and Bodenwrangen as a cross-connection give the construction the required stability and allow the addition of other elements such that due to the dimensions and shapes of the individual elements according to the drawings necessarily determined by the hull shape.
  • the screw connections are unnecessary otherwise required sweat-stitching points and thereby allow an accurate adjustment in particular of the weld seam gaps. Since for the creation of the hull according to the invention, neither outside nor inside additional clamping means are required, the outer welds can be performed in a train without obstruction or delay in an advantageous manner of welding robots with pre-programmed welding tracks.
  • an additional bonding whereby the Spantgerüst is produced non-positively in a defined distance to the finished welded outer skin.
  • the outer skin is extensively connected to the frame with the avoidance of additional stresses and visible changes on the surface of the fuselage.
  • the bond acts at the same time sound-absorbing and as thermal separation, it prevents the occurrence of crevice corrosion, increases the bending resistance of the entire structure and makes the hull a self-supporting section.
  • FIG. 1 shows a vertical section through a hull, which consists of a hull 1 and a structure 5 made as a separate unit.
  • the hull 1 and the superstructure 5 are connected to one another via a circumferential flange connection, which is formed by two identical flange plates 10 and 50.
  • the two Flanschbleche 10 and 50 do not only form a respective shaping element for the fuselage 1 and for the structure 5, but they also represent after their joining at the same time a reinforced receptacle for a circumferential Fenderprofil 2.
  • In the figure is also a part of Frame construction 51 for the structure 5 recognizable.
  • FIGs 2 and 3 each show a perspective view of the hull 1 of the hull, whose outer skin of side plates 11 and 12 - the latter not visible in the illustration - from bottom plates 13 and 14, arranged between them Chine plates 15 and 16 and a keel plate 17 and a rear end element 7 ,
  • the side plates 11 and 12 and the rear end element 7 and a front end element 8 are connected in their respective upper edge region with the forming, circumferential flange 10, wherein the connection is realized in the case of the embodiment described here by a circumferential weld.
  • FIG Fig. 3 the illustration in FIG Fig. 3 in that a framework made of frame elements is arranged in the interior of the hull 1.
  • These include first bulkhead elements 21 and 22, which are arranged on the side plates 11 and 12, and second bulkhead elements 23 and 24, which are connected to the bottom plates 13 and 14.
  • the rib elements 21 to 24 have in cross section in each case an individually folded hat profile, as in particular from the FIGS. 3 to 6 is apparent.
  • the detailed representation of an example shown Spantiatas 21 in Fig. 4 further illustrates that the end portions of the bulkhead members 21 and 22 are each chamfered and that the side surfaces 26 adjacent to the lateral surface 25 facing the ship's interior each transition into an abutment flange 27.
  • these bearing flanges 27 unilaterally open elongated holes 28 are arranged at regular intervals, which serve the welding with the plank elements 11 on which the rib element 21 is arranged in each case.
  • the abutment flanges 27 are provided with a series of injection holes 29, via which at a later time in Fig. 10 shown in detail frictional bonding of the completed bulkhead frame at a defined distance to the finished welded skin.
  • each bulkhead element 21 is provided in its lateral surface 25 with a series of indexing holes 30, by means of which the position of each individual bulkhead element 21 is uniquely determined on the associated plank element 11, which is initially unwound, ie in the plane state.
  • each bulkhead element 21 on the associated, initially still unwound plank element 11 is based on FIGS. 5 and 6 clarified. Thereafter, in each bulkhead member 21, the angles at which the side surfaces 26 are disposed on the respective lateral surface 25 are individually selected so that the side surfaces 26 after aligning and fixing the corresponding plank member 11 on the flange 10, as in Fig. 6 recognizable, perpendicular to the longitudinal axis of the hull 1 lie. Only in this state, the distances between two bulkhead elements 21 from each other, which, as in Fig. 5 recognizable when their fixation on the still unwound plank element 11 may initially be different, evenly, as in Fig. 6 is recognizable. It should be noted that the bulkhead elements 22 to 24 have an analogous construction and are also assigned to the plank elements 12 to 14 in an analogous manner.
  • FIG. 2 shows that the former frame further comprises floor panels 31 and gusset plates 32, 33 and 34.
  • the lower ends of the bulkhead elements 21 and 22 are connected via the gusset plates 32 and 33 to the upper ends of the bulkhead elements 23 and 24 and to the Bodenwrangen 31, while the lower ends of the bulkhead elements 23 and 24 are connected directly to each other via the lower gusset plates 34 , All connections are realized in the case of the embodiment described here by screwing.
  • the gusset plates 32 and 33 are analogous to the former elements 21 to 24 provided with abutment flanges in which unilaterally open elongated holes 35 for a selective welding of these gussets 32 and 33 with the associated Chine plates 15 and 16 are.
  • the production of the hull 1 takes place, as in the Figures 11 and 12 is shown in a so-called "keel up" position on a welding table 60 and begins with the positioning of the flange 10 as a shaping base for subsequently erected first outer skin elements, ie the plank elements 11 and 12 with the corresponding Spantelelementen 21, 22.
  • the bolted Gusset plates and Bodenwrangen 32 to 34 thereby convey the construction as a cross-connection the required stability and allow the addition of further plank elements such that due to the dimensions and shapes of the individual elements according to the drawings necessarily provided the intended hull shape.
  • the screw connections eliminate the otherwise required welding stitching points and allow precise adjustment, in particular of the weld seam gaps.
  • Bonding takes place only after the complete assembly of all elements and the completion of all welding work for the creation of the fuselage.
  • the shoring is created according to the design plans of the hull frictionally in a defined distance to the finished welded outer skin.
  • the adhesive process is carried out by injecting a suitable adhesive into the bores 29 of the former elements 21 to 24.
  • a metered amount 37 is introduced by means of a suitable syringe 36 into the gaps 38 between the plank elements 11 and the rib elements 21 welded to them and spreads into them Gaps and the flow channels in such a way that the adhesive is visible at the edges of the bulkhead elements 21 to 24 and thus a full-fledged and self-adapting adhesion is ensured.
  • the outer skin is connected with avoiding additional stresses and visible changes on the surface of the fuselage over a large area with the frame.
  • Fig. 13 represented on the basis of a second, identical circumferential and shaping flange plate 50 in a separate production as a second section a self-supporting structure 5 of any materials, preferably also made of an aluminum material, created and connected via the flange plates 10 and 50 with the hull 1 become.
  • the hull is constructed using a 3D CAD system and records all the individual elements in their respective use position as a compilation and as sheet metal blanks in unwound form, including the marking of the individual elements and their positioning to each other, so that in this way a modular system with high precision is formed.
  • All fuselage elements of this modular system are made of seawater-resistant aluminum sheets, preferably made of aluminum alloy EN AW 5083 (AlMg4, 5Mn, material No. 3.3547), the plank elements being cut from sheets of this alloy with a thickness of 8 millimeters.
